I hope you all can help.
I started the 73 450sl today, just getting started to load it on the trailer to go to the wash and degrease it. It always starts and it did but ran real rough. Warmed it up and put some Lucas injector cleaner in the gas. Did not smooth out. Backed it back into the garage, removed the fuel filter just to check it out. The filter seemed fine, blew through it both ways, seemed easy.
Reinstalled, removed temp sensors and cleaned with carb cleaner and reinstalled. Removed throttle control sensor wires and cleaned. checked for vac leaks. NOW it will not start. I put fuel in the intake it will start fine and run until that fuel is used. I checked the fuel pump it does not run when the key is on or when my LOVELY WIFE is turing the key. But the pump will run when I apply 12v directly to the wire lugs on the pump. WHAT is wrong?
What controls the fuel pump? ANY help Thanks
